Flooring Types and Material Comparison

Walk into any flooring showroom and you'll face a dizzying array of options, each promising to be "the best choice for your home." But here's the truth: there's no universal winner in the flooring game. That gorgeous solid hardwood your neighbor installed? It might buckle in your basement's moisture. The budget-friendly laminate? Could outlast expensive tile in your low-traffic bedroom, or fail spectacularly in your kitchen within two years. What matters isn't which material wins awards—it's which one actually fits how you live. Does your home host rambunctious pets and kids tracking in mud? Are you dealing with concrete subfloors that sweat? Will you actually commit to refinishing hardwood every decade? These real-world factors, combined with where you're installing and how much upkeep you'll tolerate, matter far more than any salesperson's pitch.

  • Solid Hardwood: Premium natural wood flooring offering timeless beauty and the ability to be refinished multiple times over decades. Increases home value significantly but sensitive to moisture and requires regular maintenance. Installation costs $8-15+ per sq ft.

  • Engineered Hardwood: Multi-layer wood construction with hardwood veneer top layer, more stable than solid wood in varying humidity. Can be refinished 1-3 times depending on veneer thickness. Costs $6-12 per sq ft installed.

  • Luxury Vinyl Plank (LVP): Waterproof synthetic flooring that realistically mimics wood or stone appearance. Excellent for high-moisture areas, comfortable underfoot, and increasingly popular for whole-house installations. Costs $4-10 per sq ft installed.

  • Laminate: Affordable wood-look flooring with photographic layer over high-density fiberboard core. Resistant to scratches and fading with easy DIY installation but vulnerable to water damage and cannot be refinished. Costs $3-8 per sq ft installed.

  • Porcelain/Ceramic Tile: Extremely durable and water-resistant option ideal for bathrooms and kitchens. Vast design options available but cold and hard underfoot, with grout requiring regular maintenance. Costs $7-20 per sq ft installed.

Frequently Asked Questions

To calculate square footage, measure the length and width of each room in feet, then multiply them together. For L-shaped or irregular rooms, divide the space into rectangles, calculate each separately, and add them together. Always add 10-15% extra for waste, cuts, and future repairs. Our calculator automatically handles these calculations and adjusts waste percentages based on your flooring type and installation pattern.
Floating floors (common with laminate and luxury vinyl plank) click together and rest on underlayment without being attached to the subfloor, making them easier to install and remove. Glue-down installation adheres flooring directly to the subfloor, providing better stability and moisture resistance but requiring more skill and time. Nail-down installation is primarily used for solid hardwood. Each method has different material and labor costs reflected in our calculator.
Professional installation costs vary by material and region: Carpet $0.50-$2 per sq ft, Vinyl/LVT $1.50-$3 per sq ft, Laminate $2-$4 per sq ft, Hardwood $3-$8 per sq ft, and Tile $5-$15 per sq ft. Additional costs include removing old flooring ($1-$3/sq ft), subfloor repairs ($2-$5/sq ft), and moving furniture. Stairs typically cost 2-3 times more per square foot than flat surfaces.
Waste percentages vary by installation pattern and material: Straight/parallel layouts need 5-10% extra, diagonal patterns require 10-15%, herringbone or chevron patterns need 15-20%, and tile typically needs 10-15% due to breakage. First-time DIY installers should add an extra 5% to these recommendations. Complex room shapes with many angles also require higher waste factors.
A complete flooring budget includes: materials (flooring, underlayment, adhesive), installation labor, transition strips and moldings, old flooring removal and disposal, subfloor preparation or repairs, furniture moving costs, and potential extras like moisture barriers, soundproofing underlayment, floor leveling compound, and new baseboards. Our calculator helps estimate these comprehensive costs.
For stairs, measure each tread (horizontal part) and riser (vertical part) separately. Standard treads are about 10-11 inches deep and 36 inches wide. Each step typically needs 3-4 square feet of material including the riser. Add 20-30% waste for stairs due to precise cutting requirements. Don't forget stair nosing (the overlapping edge) which is sold separately. Professional installation is often recommended for stairs.
Underlayment requirements vary by flooring: Laminate needs foam or cork underlayment (2-3mm) for cushioning and sound reduction. Luxury vinyl may require specific underlayment or none if it has attached padding. Hardwood uses rosin paper or synthetic underlayment as moisture barriers. Carpet requires padding (usually 7/16 to 1/2 inch thick). Tile needs cement backer board or uncoupling membrane. Choose based on subfloor type and moisture concerns.
Flooring lifespan varies considerably: Quality hardwood lasts 50-100+ years with refinishing every 10-15 years. Laminate typically lasts 15-25 years but can't be refinished. Luxury vinyl plank (LVP) lasts 20-30 years with proper care. Tile can last 50-100 years if properly installed. Carpet needs replacement every 5-15 years. Factors affecting durability include foot traffic, moisture exposure, maintenance, pets, and installation quality.
DIY installation can save 30-50% on labor costs and offers flexibility to work at your own pace, but requires tools, time, and accepting responsibility for mistakes. Professional installation provides expertise, efficiency, warranties, and problem-solving skills, typically completing projects in days rather than weeks. Consider your skill level, available time, and project complexity. Floating floors are most DIY-friendly, while tile and hardwood often benefit from professional installation.
Proper subfloor preparation is vital for flooring success. First, check for levelness - most flooring requires the subfloor to be flat within 3/16 inch over 10 feet. Test moisture levels, especially for concrete subfloors. Repair any damaged areas, replace rotted wood, and fill gaps or holes. Clean thoroughly to remove old adhesive, paint, or debris. For wood products, allow 48-72 hours of acclimation time. Budget 10-20% of project cost for potential preparation work.
For homes with pets and children, prioritize durability and water resistance. Luxury vinyl plank (LVP) is excellent - it's waterproof, scratch-resistant, and comfortable underfoot. Laminate with high AC ratings (AC4 or AC5) offers good durability at lower cost. Tile is extremely durable but hard and cold. Avoid softwood floors that scratch easily and carpet in high-traffic areas. Consider slip resistance for pet safety and choose flooring with good warranties against pet damage.
Hardwood flooring typically provides the best ROI, potentially increasing home value by 2.5-5%. Quality tile in kitchens and bathrooms also adds value. Luxury vinyl plank is increasingly accepted and can boost value when replacing old carpet or damaged flooring. Laminate provides moderate value improvement. Carpet has the lowest ROI but is expected in bedrooms. The key is choosing appropriate flooring for each room and maintaining it well. Consistency throughout living areas also enhances perceived value.
